1999 GMC Truck V8 Two Wheel Drive Automatic 130000 miles
Air works great with fan on setting 1, and setting 2.
If you go to 3 it works for maybe 10 mins. Then gets
slightly warm for about 3 mins. Then works for
another 10 mins. If you leave on 2 it works fine.
recently had check for leak--none dected--
have the same problem?
